Best OSINT tools for tracing e-mail addresses and phone numbers?

[RobMann]

Can anyone point me in the direction of the most powerful tools or best databases for gaining information from a person's e-mail address or phone number? Such as leaked databases so that I'm able to identify the individual concerned. The tools I'm finding on Google aren't returning any results at all.

For email and phone number tracing, here are some effective approaches:

Recently started using DOS-OP and honestly the data coverage is pretty extensive - pulls from social media, gaming platforms, adult sites, dating platforms, marketplaces, plus breach databases all in one search.

Found email addresses and phone numbers I wouldn't have discovered checking manually. The platform aggregation saves 2-3 hours per investigation.

They have free trial credits if you want to test the coverage yourself.

Free trial: dos-op.io --really good stuff , got me time to find it i would like to share its fantastic..

Email OSINT:
Hunter.io (business email finder)
Have I Been Pwned (breach databases)

Phone Number OSINT:
Truecaller (caller ID database)
PhoneInfoga (open source tool)
Carrier lookup services
Google search with quotes "phone number"



For PI work, always cross-verify findings from multiple sources. Single-source data can be outdated or incorrect (especially phone numbers, which get recycled).

What type of cases are you primarily working on? Different investigation types benefit from different tool combinations.
